Need Help ?
The XPS Database and The XPS Library (TXL) Websites
are
part of The XPS Research Institute Inc (501c3)
(a 501c3, domestic not-for-profit, educational institution)
that develops data, spectra-bases, software, PDF books and guidance on all things XPS.
The TXL store just opened on December 5, 2025 so we probably have some payment issues and I worry about the Subscriptions.
I was able to download both the software and a PDF handbook (digital downloads) without any issue, so far!
Actually, TXL is currently a one person operation, the founder, B. Vincent Crist, PhD, older generation!
